.PRINTING PRESS.

Applicatin filed February This invention relates t0 an ixnprovement in printing presses and particularly t0 band presses 0f the type having oscillating platens.

The object ofthis invention is t0 provide a printing press in Whl0h the gripper mechanism may be readi1y mounted and (1emounted. y

With this object in view, myinvention consists in a prining press characterized by ics provision with 21- gripping-finger shaft having a transverse sockei It'or the reception of a coupling-finger formed at the outer end 0f a reciprocating gripping:finger spring.

My invention further consists in a printing press characterized as ab0ve and hzwing certain other details of construction and combination of partsas Will be hereinafter recited in the clairns. s

In ehe adcompanying dmwings:

Fig. 1 is a broken'view in sids elevation 0f a printing press embodying 1ny invsntion;

Fig. 2 is a broken perspective view of a portion 01: the press9frame and the grippermechanism mounted thereon;

Fig. 3 is a detached perspective view 01 {ehe gripper-finger shaft; and

Fig. 4 is a corresponding view o-f the gripper-finger spring.

In carrying out my invention, as herein shown, I provide the gripper-finger sh-aft with a diaxnetrical socket 6 f01 the reception of the downWardlybent fii1ger 7 forrned at the forward end 011- a spring-arm 8, which, as W111 hereinafter appear, yieldingly 1nain tains 21 pir 01" gripperfingers 9 and 10 in spaced relationship to nhe oscillating p1aten 11 0f the press.

The gripper-fingers just mentioned am respectively monnted, by1neans 015 set-screws 12, flpon the opposite ends 0f the gripperfinge1 shaft 5 above referred-to, Which, in 1u1n, is journaled midwafy 01"; its 'Iength in a bearing-lug 13 formed upon a bifurcated platten-arm 14.

The platen 11 is pivotally monted upon 8, 1927. Sel'ia1 N0. 166,655.

by means 01 a link 19 t0 fhe upper rem= end 0f' the frame 15 aforesaid.

T0 provide a bea1ing in which the springarm 8 nmy reciprocate, the fra1ne 15 is f0rmed upon ting Ing 20having a longitudinal bezwingpassage 21 for the recePtion 01 the said arm.

A downward pr'essure upon he band-1eits side with a laterallyoflset- Ver 18 Will serve.ioswing the platen 11 toward the chase 16, so as to cause its forward face to engage the rear faces 0f the gripperwardly-bent fing'er 7 fr0m the socket 6 in the said shatft.

1. In a printing press, the combination wich the frame und oscillating platen thereof, of a transverselyarranged gripping-finger shaft carried by the Sa'id plateh, gripperfingers 1nounted upon said shaft, a transverse socket formed in said shaft, a reciprocating spring-arm providedat one ehd with anpffsetting coupling-finger adapted to enter the said socket and t0 be yieldingly held therein by the tension oi the spring-arm, and a bearing mounted upon the said frame for the reception and guidance 0f the said spnng-arm. v

2. In a printing press, the combination with the fmme anc1 oscillating platten there- 0f, 0f a transversely-mranged gripping-fin' ger shaft ca rried by the said platen, gripperfingers n1ounted upon said shaft, a dian1etrical socket formed 1n the said shaft, a remprocatmg spnngarm pr0v1ded at one end with an oflsetting coupling-finger adapted t o enter the said socket and to be yielclingly held therein by the tension 0f the spring arm, and a bearing-plug formed upon one side 0f' the said -frame for' the reception and guidance of the said spring-arm;

In testimony whereof, I have signed this specification.
